This week the White House has been lobbying Congress to raise the $14.3 trillion federal debt ceiling. Doing so would give the government the legal authority to borrow billions of dollars to pay its bills.
Although refusing to raise the ceiling would be an almost unprecedented move, some conservatives argue it's the only way to get federal spending under control.
The Treasury Department says that if the limit isn't raised by Aug. 2, the government will run out of money to operate.
